I'm using JSTl to get all data in list from Spring, i can get all data, but i only want to get one in a lot of duplicate data

this is my code in JSTL/JSP:

<c:forEach var="list" items="${listDeliveryNote}" varStatus="status">
      <td>${list.rcvlocdesc}</td>
</c:forEach>

When i run and get value following as from table:

C510-CDB_Him Lam
C510-CDB_Him Lam
C510-CDB_Him Lam
C510-CDB_Him Lam

But i only want to get 1 row in duplicate data is: C510-CDB_Him Lam

So how to can get one row in duplicate data in List with JSTL ? (not use SQL)

Thank a lot

Hint: You have to store data in `HashMap` instead of `ArrayList` or `LinkedList` – Faeem azaz Bhanej May 10 '22 at 09:35
@FaeemazazBhanej: of course, i have stored list in HashMap – Khanh Van Luong May 10 '22 at 09:37
Your `List` is key? – Faeem azaz Bhanej May 10 '22 at 09:40
just i want to use JSTL for this case – Khanh Van Luong May 10 '22 at 10:13
Can you show me your `controller` where hashmap is? – Faeem azaz Bhanej May 10 '22 at 10:20
You can pass to jstl the `Set` of values you are interested , so it is guaranteed all values are uniques. – dariosicily May 10 '22 at 10:38
@dariosicily: could you give me detail with 'set' ? – Khanh Van Luong May 10 '22 at 10:40
[`Set`](https://docs.oracle.com/javase/8/docs/api/java/util/Set.html), if you put inside it the values , all of them will be always uniques. – dariosicily May 10 '22 at 10:42
